My 1996 A4 2.8 12v auto always had TERRIBLE (12 mpg!!!) gas mileage (ok, city driving; but still, compared the 2 stage 3 1.8T I have, I'd say HALF the gas mileage).

The B2S1 O2 sensor is acting up since a while. But also had misfires (and well yes, daughter ran the tank dry last week).

But of concern were the misfires. I logged timing and knock values, and they look weird to me.

Can someone please comment what is going on? Car always starts and runs actually quite smooth.
